IMPROVEMENT IN GRAlNlNG-ROLLERS.

Specication forming part of Letters Patent No. 183,051, dated October 10, 1876 application filed March 6, 1876.

' .To all whom it may concern:

of Chicago, in the county of Cook and State of Illinois, have invented an Improved Grainiug-Roller, of which the following is a specitication:

In graining the surfaces of pictureframes, panels, and other work, in imitation of French hurl veneers, it has been customary heretofore to use a coarse flat sponge, which was pressed by hand one or more times upon the fresh or green color. The object I have in View is to provide a rollenwithwhich the burl surface can be imitated inone-tenth the time heretofore required; and tu this end it consists in covering a suitable roller with coarse sponge, secured thereon in a layer of uniform thickness.

Figure l is a'perspective view of my device. Fig. 2 is a longitudinal section of the roller.

In the drawing, A represents a hollow cylindrical roller, axially journaled by pins a a, in

the jaws ot' a frame, B, provided with the handle G. The roller is covered with a layer, A', of coarse sponge, made of a sheet of a thickness as nearly uniform as possible. The roller so covered is to be moistened with wa- Jrer, if watercolors arc used, or with turpentine, if the graining is executed in oil-colors, and rolled once or twice over the green color, when the irregular burl will be so closelyr imitated as to deceive all but experts, in a small fraction of' the time required to execute it by the process heretofore used.

I am well aware that graining pattern-rollers are not new, and, while I disclaim, broadly, the invention of a graining-roller,

What I do claim as new is- A graining-roller covered with sponge for imitating French-walnut burls, substantially as described and shown.
